March 13, 2016 This day is not equal to 3600*24 seconds?

Find a bug in your job:

My company server PHP default timezone and timezone are configured to America/los_angeles;

Time Stamp 1457856000,

Formatted with the date () function is 2016-03-13 00:00:00;

But after adding 3600*24-1 seconds to the timestamp, the date () function was used to format the discovery as the 2016-03-14 00:59:59;

The day before and after the date did not have such a strange phenomenon;

Does anyone know why?

/** * 按照你说的时间，应该就是这个时区， * 但是没什么问题，是你的计算过程出现什么没有注意到的地方， 还是不同的时区的关系 */date_default_timezone_set('Etc/GMT+8');$timeStamp = 1457856000;var_dump(date('Y-m-d H:i:s', $timeStamp));var_dump(date('Y-m-d H:i:s', $timeStamp + 3600*24-1));

Not very understanding of your problem ... The initial suspicion is due to other calculations.

There is a concept called Daylight saving time ~
